1. ATTACHED TOOLS
FEMALE: the attached tool of drawbead groove. Click SELECT button to display the Select Part dialog box illustrated in Figure 11.4.43. After a part is selected, the program will generate a drawbead groove on the attached tool mesh. Click REMOVE button to cancel the Attach relationship.
Figure 11.4.43 Select Part dialog box
MALE: the attached tool of drawbead. This is the default lock tool when defining Line Bead.
2. CENTER LINE
This list lists all the drawbead center lines used in geometry BEAD1. The program will select a series of connected drawbead center lines by default.
ADD: add drawbead to the list. Click this button to display ADD region illustrated in Figure 11.4.44.
Figure 11.4.44 Add drawbead dialog box
SELECT BEAD FROM WINDOW: Select drawbead in screen area using mouse cursor. Click this button to display Select dialog box to prompt the user to select drawbeads. Click the left mouse button to select, the middle button to confirm and the right button to cancel. The selected drawbeads will be added to the drawbead center line list automatically.
SELECT LINE…: Select a drawbead center line which is used to create drawbead line and add it to the list on the right side. click this button to display a Select Line dialog box to prompt the user to select line.
IMPORT: Import a drawbead center line which is used to create drawbead and add it to the list on the right side. The formats of the imported files are *.cur and *.iges.
The user may select the drawbeads to be added from ADD list and click FINISH button to add the selected drawbeads to the center line list.
REMOVE: Remove the line beads in the list. This button is enabled after selecting the drawbeads in the list.
REVERSE: Reverse the material flowing direction. This button is enabled after selecting the drawbeads in the list.
2. SHAPE
Once a drawbead is selected in the above mentioned center line list, the profile shape region of geometry bead will be displayed in the Geometry Bead page, as illustrated in Figure 11.4.45. The user may select drawbeads from one or multiple lists and define their profile shapes. Refer to Section 3 for definition of control parameters.

3. TRANSITION
Set the transition parameters of geometry bead.
TOLERANCE: the distance tolerance between two drawbeads. If the distance between adjacent end points of two drawbeads is less than this value, it will generate transition geometry shape between two drawbeads when generating geometry bead. Otherwise, it will generate end points respectively. The default is 1.
LENGTH: the length of transition region. The default value is 25.
After finishing the above setup, click APPLY button to generate BEAD1 according to the geometry shape defined by the user.
ADD: Add geometry bead BEAD2, BEAD3, etc.
DELETE: Delete the selected geometry bead.
REMOVE: Only remove the mesh of the selected geometry bead. This operation can only be performed from the end to the beginning, which means to delete the mesh from BEAD3 to BEAD1. Click this button to display a Warning dialog box illustrated in Figure 11.4.46. Click Yes to remove the drawbead mesh.

EDIT: Edit the section shape of drawbead. This button is enabled after generating the geometry bead. Click this button to display a Warning dialog box illustrated in Figure 11.4.47. Click Yes to re-edit all the section shapes in the current geometry bead

After defining the geometry bead, the program will automatically hide line bead and shied the effect of line bead. The user does not have to do anything to the line bead.
NOTE: When switching between different drawbeads, the program will adjust mesh status in time. If switching to the line bead page, the program will restore mesh to the line bead status; if switching to geometry bead page, the user need to update the mesh manually again.
